A
GFCI (ground-fault circuit interrupter) shuts off power when current leaks to ground, which protects
people from shock, especially near water. An
AFCI (arc-fault circuit interrupter) shuts off power when it detects dangerous arcing in wiring, which protects your
home from fire. Many homes need both, and dual-function devices do both. Want help? See our
lighting, outlets & gfci service.
What a GFCI Does
It compares current going out and coming back on a circuit. If even a small amount leaks, for example through a person touching a faulty appliance near water, it cuts power in a fraction of a second.
What an AFCI Does
It watches for the electrical signature of arcing, the sparking that happens at damaged wires, loose connections and crushed cords. Arcing is a common cause of electrical fires.

Where Each Is Required
| Location | Protection |
|---|
| Bathrooms, kitchens, laundry, garages, outdoors | GFCI |
| Bedrooms, living rooms and most living areas (new or extended circuits) | AFCI |
| Kitchens and laundry areas | Often both, under current code |
Requirements depend on the code in effect where and when the work is done.
Outlets or Breakers?
GFCI protection can be an outlet or a breaker. AFCI protection is usually a breaker. Dual-function AFCI/GFCI breakers protect a whole circuit at once.
Adding Them to an Older Home
Older LA homes often have neither. Adding GFCI protection near water is one of the most worthwhile safety upgrades. AFCI breakers depend on your panel brand and condition.
